Hello there mr ojenbe. Its most likely you hb setting (hold back) it means the profile wont run unless the temperature is within the + or - the hb setting. Considering you most likely wont be going above 230 set hb to 230. You set this in your where you set your profiles its one setting for all profiles so you change one you change them all it is the last setting when you set the profile.

Re: Altec PC410 wiring problems

Hi...as per my observation you need two switches one for on and one for off. Have tried to see if anything works yet . your pre heat switch wiring dont look right to me? Dose your rex 100 have ssr output or have you modded it.

All Rex C100's have been modded. One's on Ebay that come with SSR output have had the relay removed and jumpers put in place. They just crisscross the jumpersto put the 12vdc positive at terminal 4 to stay consistent with the polarity of other REX models that actually do have SSR output originally. When BGA guys buy aRex C100 with relay output and mod it to have SSR output, they put the jumpers parallel, which puts 12vdc positive at terminal 5, like in the schematic shown inthe very first post of this thread.
